Perhaps you should try some spelling variations:
hyoung kim » hyung kim, yong kim
hyoung il » hong il
thi chang » chin chang, thi hong, thi thanh
dan yang » daun yang, tan yang, wang yang
yang thi » dang thi, yang chik, yang di
chang ha » chang mae
hua dan » hua ban
wang » wing, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) ((hyoung kim) OR (hyoung il)) hua dan yang thi chang ha ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((hyoung kim) OR (hyoung il)) hua dan yang thi chang ha ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((hyoung kim) OR (hyoung il)) hua dan yang thi chang ha ;*.
